The city famous for getting the green (as in "cash") is now going for the green in another way.

Several of the biggest casino companies are aggressively pursuing the so-called "green initiatives" aimed at preserving the environment through sustainable business practices.

Not that they're there yet, but in a recent in-depth report by Newsweek, which ranked the top 500 green companies in America, three Las Vegas casino companies made the cut: Las Vegas Sands at No. 128, MGM Mirage at No. 184 and Wynn Resorts at No. 176.

Leading the way for LV Sands is Palazzo, currently the highest rated Leadership in Energy and Environmental Design (LEED) building in the nation, with CityCenter striving to achieve LEED certification for all of its elements.

And while it didn't make the list, Las Vegas' oldest casino, the Golden Gate, is holding up its end by switching entirely to geothermal power for its hot water.

Breakfast Bounced

M Resort has eliminated breakfast in its buffet. The good news is the lunch and dinner buffets are still among the best in town.

Brasserie Bolting

Daniel Boulud Brasserie, the Las Vegas outpost of the star chef for whom it's named, will close in April when its five-year operating agreement with Wynn Las Vegas is up. No word yet on what will take its place.

Good PR

The Orleans has an outstanding deal on a complete prime rib dinner in the Courtyard Café. It comes with an 8-ounce cut of meat (with au jus and horseradish), soup or salad, choice of potato, rolls, dessert, and a drink -- for $9.99. The dessert alone is worth half what you pay, since you choose from the full dessert menu, where hot-fudge sundaes, root-beer floats and cheesecakes start at $4.49. The special runs Monday through Friday from 2 to 6 p.m.
